FRIDAY, Sept. 23 (HealthDay News) -- Although some studies have
suggested that men can find clues to women's reproductive status by
certain changes in their voices, a new study appears to dispel that
There is no reliable way to determine when women are ovulating
by examining changes in their voices over the course of a month,
the researchers concluded.
Unlike previous studies, the researchers behind the new study
examined changes in women's voices throughout the entire menstrual
cycle for hints on reproductive status, particularly the increased
likelihood of conception.
The study, published in the current issue of the journal
PLoS ONE, found the variations in women's voices during the month do not reliably predict ovulation. Although the researchers did find that women spoke in the highest tone (which some studies have associated with attractiveness) right before ovulation, their voices also rose to those same high levels right after ovulation.
The study found, however, that men had a very slight preference
for pre-ovulation voices over voices recorded during ovulation. The
researchers concluded that information about women's reproduction
is "leaked" -- not broadcast.
Although women's voices do not announce that they are ovulating,
the study's authors pointed out something men may already be well
aware of: Women's voices are harsher and more irregular during
